Bentonite is a geological clay material that is mainly made up of a mineral group called montmorillonite. It is usually created from volcanic ash that has been disintegrated by water. Other minerals included in bentonite clay are aluminum, calcium, potassium, and sodium. The predominance of one of these minerals dictates the names of the variants.
BENTONE SDÂ® 1 is an organic solventborne derivative of a bentonite clay. It is a very easily dispersible additive for systems containing primarily aliphatic and other non-polar to medium-polarity solvents.BENTONE SDÂ® 1 can be added at any point in the paint manufacturing process and can be used for post-correction.t is a very easily dispersible additive for systems containing primarily aliphatic and other non-polar to medium-polarity solvents.BENTONE SDÂ® 1 can be added at any point in the paint manufacturing process and can be used for post-correction.
